    I am mostly fiscally conservative and like government out of industry. However, industry has shown over and over that it will take shortcuts for profit at the expense of the health of the people and be completely irresponsible and immoral. While I respect the goal of a vibrant free market, government regulation and the civil and criminal fines and sentences around them, are absolutely necessary to restrain abuses. The chemical and food industries are great examples of where this is necessary.

    The recent financial crisis also illuminates an area where more regulation and oversight is needed. My particular gripe was in the area of rating the creditworthiness of the CDOs, etc. That completely failed to specify risk in the valuation of these financial artifacts.

    Sorry for making this side trip even more off topic to the thread.

    not far off topic, people need to know that there are inherent risks in everything....

    Re: Huge blast at Japan nuclear power plant

    Did anyone notice the large shock wave, where water is forced out of the air by pressure, that preceded the ‘smoke’ of the explosion? Generally you only see this with a high explosive. I don’t think I’m getting an accurate description from the nukes management.

    How about dust? If my house exploded, there would be a lot of dust in the air. It was built in 94, so it isn't that old. I climbed into the attic last week to place a TV antenna. Almost puked from all the dust I stirrred up...

    Dust, it’s not about the dust?
    The explosion was not like a vessel of some sort failing under pressure; it was more like a bomb. I’m thinking the reactor it toast, in pieces, inside what is left of the containment vessel.

    I have been involved in nuclear power since 1966....if the reactor vessel exploded, all the water would have turned to steam, and all the shielding provided by the water would be gone, and the operators dead or dying.
    Give it some time....you'll see that a meltdown is probably all that will happen.

    I’ll wait. So what do think caused the pressure wave that preceded the expulsion of material at the beginning of the explosion?

    I have read several reports that small amounts radioactive Cesium has been measured in the atmosphere. The only way that cesium can be produced is if the fuel rods are actually burning. This confirms that a partial meltdown is already underway. But understand this - 3 Mile Island was also a partial meltdown, and was not the disaster it could have been. If this can be held to a partial meltdown, it won't be relative that bad. However, one report I have read is that the Japanese are running seawater into the reactor. This is a hail Mary pass, and if it doesn't work, and it becomes a full meltdown, then the only alternative left will be to bury the reactor in sand and cement.

    Uhh, maybe it was all the hydrogen?

    It also wasn't in Russia... but true, the infrastructure hadn't taken a hit, but the design of the reactor is alo fundamentally different....
